Australian BioResources Pty Ltd is a state-of-the art facility for the breeding and holding of research mice, owned and operated by the Garvan Institute of Medical Research on behalf of the medical research community of NSW.

The facility provides capacity to house the rapidly increasing number of “lines” or varieties of genetically modified mice that underpin progress in modern medical research. These colonies are critical for progress in research across all health priority areas, including cancer, mental illness, arthritis, asthma, heart disease, diabetes and obesity.

Mice held in the facility are "owned" by individual research groups, but managed and cared for by the highly trained staff of the facility. They are shipped to the relevant institution when needed for research. Research institutes and universities who have reserved space within the facility are known as Partner Institutes. Mice bred in the facility are Specific Pathogen Free, so they are free of diseases that may impact on animal welfare and experimental results.
